【摘要】 论文在全面总结国内外在UPS电源管理及UPS故障诊断方面发展情况和研究现状的基础上，分析了目前在UPS故障诊断方面存在的问题。采用专家系统理论和故障树理论，研究、设计、开发和建立了一个基于知识的UPS故障诊断专家系统。为UPS故障诊断提供了一种新的分析方法，其研究对于UPS故障诊断和整机安全运行评估具有重要的实际意义和一定的理论指导意义。本论文的工作旨在建立一个基于知识的UPS故障诊断专家系统，是根据UPS故障特点进行开发和设计的。该系统采用了分层次、故障树推理诊断模型，并结合了其它的故障树分析和诊断方法，能对UPS常发生的各类故障进行分类、分析，从而更有效地完成UPS不间断电源的管理和故障诊断。UPS故障诊断专家系统采用了先进的客户机/服务器的网络模式，选用了PowerBuilder 7.0作为应用程序的开发工具，数据库采用了当前性能优秀的数据库平台Sybase，并对专家系统中数据库和知识库的设计进行了优化。该文提出的基于知识的UPS故障诊断专家系统具备了较好的功能。· 可根据最新一次的数据进行UPS的状态分析和故障诊断；· 可根据专家经验对专家系统知识库中的各类知识进行动态修改；· 具有UPS用户或用户组管理、维护的功能；· 可进行各类UPS部分特征量处理信息的查询；· 可对UPS部分特征量进行历史分析。为方便用户的使用，还设计了友好的用户界面。更多还原

【Abstract】 On the basis of the development of UPS management and the Expert Systems of fault diagnosis for UPS, with the theory of Fault-tree and the theory of Expert Systems, the dissertation has designed and built up an Expert System based on the knowledge of fault diagnosis for network UPS, which would be a new method of fault diagnosis for UPS and would be of great practical and academic value for the general safety assessment of UPS. The object of the dissertation is to build up an Expert System, which is designed according to the characteristic of the UPS fault data. And the Expert System has introduced the fault-tree analysis and other analysis methods, and classified the types of UPS faults, in order to realize the management and fault diagnosis for UPS effectively. The Expert System has adopted the client/server network mode, and introduced PowerBuilder 7.0 and Sybase as the development method and database, and improved the design of database and knowledge warehouse, which made the Expert System function better, for instance, to analyze the state and fault diagnose on the base of the latest data, to perfect the knowledge in the Expert Systems, to manage and maintain the UPS, to inquire and to analyze through the characteristic data. At the same time, the author has designed a friendly UI (user interface).更多还原
